The nickname for wooden billets is BamBam sticks. They should look like BamBam's club. Just draw knife the end small enough for you to hold comfortably. If you want to harden them, hold them over a fire until they start to char. FWIW, James Parker is the only person I know who can fire harden them properly. Tallahatta works well with wood, working well with wood takes a lot of practice. Bill
